函数是中学数学的核心内容,是贯穿整个中学数学的一条主线,它似一根纽带,把数学的各个分支紧紧地联系在一起.一次函数、反比例函数、二次函数是初中阶段函数学习的重点内容,但在近几年的中考试题中,分段函数图象应用题的身影屡见不鲜,而大多数学生一见到这类题就懵,看不懂图象是什么意思,不知从何处入手,造成了丢分.因此,解答分段函数图象应用 Function is the core content of high school mathematics, it is a main line that runs through the whole middle school mathematics, it seems to be a link, the various branches of mathematics are closely linked together.Function, inverse function, quadratic function is the function of the middle school However, in the middle school entrance examination questions in recent years, the application of the segmentation function image is not uncommon, and most students see such questions at a glance, do not understand what the image means, I do not know where Starting, resulting in lost points.Therefore, the application of the segmentation function image
